基于流体饱和多孔隙介质波动方程的时间推移地震反演
|
摘要
针对二维流体饱和多孔隙介质波动方程,设计了自适应同伦法和小波-自适应同伦法,在此基础上,将局域化思想引入时间推移地震反演,并使用小波-自适应同伦法和自适应同伦法反演两次监测数据,提出了一种适用于时间推移地震勘探的局域化反演算法.为了验证新方法是可行的,文中把它应用于同一地点不同时间的观测模型,通过数值实验表明了这种方法的有效性.
In this paper,we propose a localized strategy using the wavelet-homotopy method and the adaptive-homotopy method as the interpretation tool for time-lapse seismic inversion.In order to testify the new method′s feasibility,we apply the method to wave equations of fluid-saturated porous media.The numerical results show that the new method is effective.
